Diverse crystalline products are extremely various concerning their hardness along with other Attributes, which establish with which solutions And the way simply they are often Lower and polished with top quality.
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
The host crystal is a lot more than just a means to repair the laser-active ions at certain positions in House. Quite a few Attributes with the host material are essential:
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
The most attainable doping concentration can depend strongly within the host materials and its fabrication process.

GWU-Lasertechnik has in excess of thirty years of knowledge in distributing laser crystals. Opt for GWU to gain from our extensive understanding As well as in-subject working experience!
In addition, some versatility is dropped in experiments if a person simply cannot Check out absorbers with various thickness or doping concentration, for instance, with out exchanging the laser crystal itself.
作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：
晶体生长 晶体加工 镀膜能�?品质管理 研发能力 新闻中心
These tables comprise only the commonest host crystals; numerous Some others exist, that are fewer commonly made use of.
Here it is possible to post queries and remarks. As far as they get approved through the author, they're going to show up earlier mentioned this paragraph together with the creator’s answer. The writer will decide on acceptance according to certain requirements. Effectively, the issue must be of adequately broad interest.
A couple of laser crystal elements are already demonstrated wherever some saturable absorber material is integrated for passive Q switching of a laser.
Not surprisingly, it is vitally attractive that a specified crystal excellent is generated persistently, Though various laser layouts may have another sensitivity to content parameters.
There's a wide range of crystalline media, that may be grouped according to big atomic constituents and crystalline constructions. Some essential teams of crystals are:
With That idea, a single click here does not have to have an extra saturable absorber crystal, to ensure that a single may possibly make a lot more compact Q-switched laser setups with lessen inner parasitic losses. Having said that, unwanted Unintended effects might also arise, such as getting unwelcome valence states of the concerned ions or Vitality transfers.

Laser crystals are optical crystals �?usually single crystals (monocrystalline optical supplies) �?which might be made use of as acquire media for sound-condition lasers. Typically, They are really doped with possibly trivalent unusual earth ions or transition metal ions.
激光晶体（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。
